COR-Medical Expands the Sonicision™ Product Line: Two Versions for Different Surgical Needs
The COR-Medical portfolio includes two versions of Medtronic's cordless ultrasonic dissection system: the standard Sonicision™ and its updated generation, Sonicision™ 7. While the standard model is designed for sealing and cutting vessels up to and including 5 mm in diameter, Sonicision™ 7 extends this capability to vessels up to 7 mm in minimum energy mode.
The updates go beyond vessel diameter. Sonicision™ 7 features an upgraded generator, increased battery capacity, and improved dissection speed and jaw temperature profile. At the same time, the system retains the key advantage of the product line — a fully cordless design.
Two Sonicision™ Versions in the COR-Medical Portfolio
Standard Sonicision™ — for Vessels up to 5 mm
The standard Sonicision™ is a cordless Medtronic ultrasonic dissector designed for soft tissue dissection, sealing, and cutting of vessels up to and including 5 mm in diameter. The system is intended for use in both open and minimally invasive surgery.
The instrument features a tapered, curved jaw that facilitates access to anatomical structures in confined spaces. The active blade is 14.5 mm long, with a width of 1.7 mm at the base and 0.8 mm at the tip. The shaft rotates 360°, allowing the working end to be positioned according to the surgical approach.
The standard model is available with four shaft lengths: 13, 26, 39, and 48 cm.
Sonicision™ 7 — An Updated Generation with Expanded Capabilities
Sonicision™ 7 is an updated version of Medtronic's cordless ultrasonic dissection system. Compared with the standard Sonicision™, the new version combines an expanded vessel sealing range with improved dissection speed, temperature profile, and power system performance.
One of its key functional differences is the ability to seal and cut vessels up to and including 7 mm in diameter in minimum energy mode. In maximum energy mode, the system is designed for vessels up to and including 5 mm in diameter.
A dual-mode tactile button on the handpiece provides intuitive control. Surgeons can switch between energy delivery modes without taking their attention away from the surgical field.
The updated Sonicision™ 7 generator (SCG7AA/SCG7AB) features a sealed design and is compatible with automated washer-disinfectors and autoclave sterilization. Its expected service life is up to 150 procedures.
The new version is available with four shaft lengths: 13, 26, 39, and 48 cm.
How Sonicision™ 7 Differs from the Standard Version
Both models use ultrasonic technology and feature a cordless design. However, the updated Sonicision™ 7 generation incorporates several functional and technical improvements.
| Feature | Sonicision™ | Sonicision™ 7 |
|---|---|---|
| Vessel diameter in minimum energy mode | Up to 5 mm | Up to 7 mm |
| Vessel diameter in maximum energy mode | Up to 5 mm | Up to 5 mm |
| Technology | Ultrasonic dissection and coagulation | Ultrasonic dissection and coagulation |
| Design | Cordless | Cordless |
| Shaft lengths | 13, 26, 39, 48 cm | 13, 26, 39, 48 cm |
| Generator | SCGAAS | SCG7AA / SCG7AB |
| Generator service life | According to the documentation for the respective model | Up to 150 procedures |
Benefits of the Updated Sonicision™ 7 Generation in Surgical Practice
The improvements in Sonicision™ 7 go beyond the ability to work with larger-diameter vessels. Medtronic has also enhanced dissection speed, the instrument's temperature profile, and power system components.
1. Sealing and cutting vessels up to 7 mm
In minimum energy mode, Sonicision™ 7 provides sealing and cutting of vessels up to and including 7 mm in diameter. In maximum energy mode, this capability extends to vessels up to 5 mm. This expands the instrument's range of applications compared with the standard Sonicision™.
2. Increased dissection speed
Sonicision™ 7 demonstrates 24% faster dissection during repeated activations in maximum energy mode, according to Medtronic's comparative test results. This may be relevant when working with dense tissues and performing successive maneuvers.
3. Improved sealing performance
In comparative testing using a renal artery model, Sonicision™ 7 demonstrated a 14% higher burst pressure. This parameter characterizes the strength of the seal under test conditions.
4. Optimized temperature profile
The updated working-end design provides improved temperature characteristics, according to Medtronic data:
-
the maximum temperature of the inactive jaw is 20% lower;
-
the cooling time of the inactive jaw after repeated activations is 29% shorter.
These characteristics are important when working near anatomical structures sensitive to thermal exposure. However, they do not replace the need to follow the manufacturer's recommended instrument-use technique.
5. Updated generator and simplified reprocessing
The SCG7AA/SCG7AB generator is designed for up to 150 procedures. Unlike the previous generation, it is compatible with automated washer-disinfectors (autowashable) and autoclave sterilization in accordance with the manufacturer's instructions.
6. Increased battery capacity
The reusable SCBA battery has 88% greater capacity compared with the previous-generation battery and is designed for up to 200 procedures. This provides a greater energy reserve for longer surgical procedures.
7. Cordless design and one-button control
The absence of cables provides freedom of movement within the sterile field, simplifies instrument exchange, and helps optimize the operating room workspace. The dual-mode activation button allows surgeons to control energy delivery directly from the handpiece while maintaining focus on the surgical field.
